- Both you and your fiancé(e) must be legally free to marry. This means that any previous marriages must have been legally terminated through divorce, death, or annulment.

- You and your fiancé(e) must have met each other in person at least once within the past two years, unless you can demonstrate that meeting in person would violate strict and well-established customs of your fiancé(e)'s foreign culture.

- You and your fiancé(e) must have a bona fide intention to marry within 90 days of your fiancé(e) entering the United States. This intention must be genuine and not for the sole purpose of obtaining an immigration benefit.

Once the Form I-129F is approved by USCIS, it will be sent to the U.S. Embassy or Consulate in the country where your fiancé(e) resides. Your fiancé(e) will then need to apply for a K-1 visa and attend an interview at the embassy or consulate. During the interview, your fiancé(e) will be asked about the relationship, their intent to marry, and other relevant details.

If the visa is approved, your fiancé(e) will be able to travel to the United States. Once in the country, you and your fiancé(e) must marry within 90 days. After the marriage, your fiancé(e) can apply for adjustment of status to become a lawful permanent resident.

Applying for a Fiancé(e) visa can be a complex process with many requirements to fulfill. It is recommended to consult with an experienced immigration attorney to guide you through the application process and ensure that you meet all the necessary eligibility criteria. By following the proper procedures and demonstrating your intent to marry a U.S. citizen, you can successfully obtain a Fiancé(e) visa and begin your life together in the United States.
